Google's doing their Summer of Code program again this year. We missed last years', but I'm going to try signing us up as a mentoring organization this year.
Feel free to put any relevant-sounding project ideas here: http://meta.wikimedia.org/wiki/Summer_of_Code_2006
Mozilla's experience last year wasn't so good[1]; some of their projects didn't complete, and most of them haven't been touched since the end of the summer. Mono however had a much more positive experience[2], with most of their projects completing and being further developed and adopted after the end.
So I think it will be important to try to engage the folks working on our projects if we want to keep them. :)
